Answer:
t=27725.8minutes
Explanation:
To determinate use the law the change of volume in determinate time is derivate so:
The flow in is zero and the flow out is modeling with V as the volume out in the volume of the lake in the reason of change.
Integrate to get the volume function
The find the constant C in the time t=0 the volume is knowing so:
The volume is 1 part per million so:
The answer is (B 60N) hope it helps and have a good day!
The correct answer to the question is unbalanced .
EXPLANATION:
As per Newton's first laws of motion, we know that a body at rest will be at rest or a body moving with uniform velocity along a straight line will keep on moving with the same velocity along that line unless and until it is compelled by some external unbalanced forces acting on.
Hence, it is the unbalanced force which is responsible for creating the motion on the body.
As per the question, Anne applied some force on the toy car. It is called applied force. There is also frictional force between car and the surface which opposes the motion of the car. The toy car will move due to the net force acting on it. The net force is known as unbalanced force.
